The tank includes an outlet pipe extending through the shelter for permitting the emptying of the tank during use of the facility. The shelter includes exterior structural members to minimize the number of dirt-collecting corners and edges in the interior.

PORTABLE TOILIIT The use of portable sanitary facilities becomes necessary in areas where permanent installations are not available, such as on construction sites. In the past, such facilities have included a waste-storing tank atop which a toilet seat ismounted. The problem with present day facilities of this sort is that the facility must be shut down during the emptying of the waste tank. Also, previously conceived and constructed designs include shelter structural support members which produce a large number of edges and corners that have a tendency to collect dirt and generate an unclean surrounding.

With the present invention, the waste storage tank is provided with an outlet pipe which extends outwardly through the wall of the shelter so that the tank may be emptied without the necessity of shutting down the facility. Further, the structural members of the shelter are disposed on the exterior in order to minimize the number of edges and comers in the interior of the shelter. In summary, the concept of the present invention is directed to rendering a sanitary toilet facility with a minimum of maintenance.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a perspective view of the shelter which encloses the toilet facility of the present invention.

FIG. 2 is a transverse sectional view taken along a plane passing through section line 2-2 of FIG. 1.

FIG. 3 is a longitudinal sectional view taken along a plane passing through section line 3--3 of FIG. 2.

FIG. 4 is a horizontal sectional view taken along a plane passing through section line 44 in FIG. 3.

Referring to the drawings, and more particularly FIG. 1 thereof, FIG. 1 illustrates the external view of a portable toilet facility including a shelter or enclosure having base support braces 12 and planks l4'disposed transversely of the brace ends to form a step. A panel 19 is suitably fastened to a set of associated comer uprights 18 and a center strut 17 to form the lateral wall structure for the shelter 10. The upper horizontally disposed edge of the panel 19 includes an opening formed therein which is covered by a screen 20 to permit air circulation through the shelter and has a flap 21 mounted by hinges to the panel 19 which can be closed in foul weather. A front panel 22 is supported by the base braces 12 and is connected along lateral edges thereof to the lateral panels 19. The front panel 22 includes a rectangular opening 24 formed therein to accommodate a door 26 which serves as an entrance and exit to the facility. The door is mounted by hinges 28 to the front panel 22.

In order to achieve ventilation through the shelter, the front panel 22 and a similarly dimensioned rear panel include arcuate top edges to permit the mounting of a curved roof 30 thereto. The roof includes an opening 32 to permit the passage of an outwardly screened ventilator pipe 34 through the roof for purposes to be described hereinafter.

Considering FIGS. 2 and 3 of the drawings, the interior of the toilet facility includes floor joists 36 laterally disposed in spaced parallel relation to provide support for flooring planks 40. A water closet cabinet is provided which includes a front panel 42 extending the length of the planks 40. A cabinet top 44 is disposed above the panel 42 and has a centrally formed opening 46 therein.

Referring to FIG. 2 there will be shown a waste tank disposed inside the cabinet, the tank being indicated by 50 and including an opening in the upper portion thereof to which a sleeve 48 is welded or otherwise suitably attached. The upper end of the sleeve 48 is in juxtaposition with the underside of the cabinet top 44 in concentric relation with the opening 46 in the cabinet top. A c lindrical liner 49 is removably mounted in the sleeve and as an annular collar on the upper end thereof which abuts the top edge of opening 46.

The underside of the tank 50 is supported by a contoured elongated collar 52 having angle brackets 54 connected at transverse ends thereof to provide a secure seat for the tank.

With further reference to FIG. 2, there will be shown an outlet pipe or nipple 56 having an outwardly disposed and removable cap 58. As will be noted, the end portion of the outlet pipe 56 passes through the shelter panel 19 to permit the emptying of waste material from tank 50 without shutting down the facility. A flow value 60 is connected in line between the tank 50 and the outlet pipe 56. A covered port 61 allows access for maintaining valve 60.

The present invention may be utilized with conventional toilet flush apparatus or tank-sealing means usually associated with portable toilets of the type described. In order to provide venting of the tank 50, an opening in collar 62 is disposed adjacent sleeve 48. A vertically oriented pipe 64 is connected at a lower end thereof to the collar 62, the upper end of the pipe passing through ceiling 30 to terminate in the vent 34. Provision of such venting means results in relatively odor-free operation of the toilet facility as well as providing venting of the tank 50 during the emptying thereof at a time when the toilet is being utilized.

Referring to FIG. 3, there will be noticed a urinal 66 having an upper chemical storage tank 67 which feeds the lower urinal receptacle 7], through fitting 65, with a sanitizing and deodorizing chemical. The urinal includes mounting flanges 68 attached thereto. The flanges are disposed against the interior of panel 19 and fastened to an exteriorly disposed horizontal panel strut 69 by appropriate hardware 70. A drainpipe 72 is connected at its upper end to the urinal 66 and includes an intermediately disposed elbow portion which extends to a right angle portion terminating at the outward end thereof in a fitting 74 at the tank 50. Thus, the toilet facility may accommodate two individuals at the same time.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

What is claimed as new is as follows:

1. A toilet facility comprising a shelter having support means at the bottom thereof for supporting said shelter on a relatively flat surface, a tank mounted in the bottom of said shelter adjacent said support means, an opening formed in the tank, a toilet seat, means connecting the toilet seat in communicating relation with the opening in the tank, tank vent means connected to said tank, outlet means connected to the tank for permitting forced emptying of the tank contents during use of the facility, an opening in said shelter, said outlet means extending through said shelter opening to the exterior of the shelter, said outlet means including valve means in said shelter for controlling the flow during forced emptying, and a port in said shelter adjacent said valve means for permitting access to said valve means for adjustment thereof, said valve means being normally closed and being opened for forced emptying of the tank, said facility being operative during the forced emptying operation.

2. The toilet facility set forth in claim 1 together with urinal means mounted in the interior surface of the shelter, a chemical storage tank positioned atop the urinal means for flushing the latter with a sanitizing and deodon'zing chemical, and a drain pipe connecting the urinal means to the tank.
